MADE IN INDONESIA, Tuned for each Antenna. On its own design, Helical has 180ohm impedance which is not matched with our FPV system with 50ohm impedance. Hence so-called helical tuning is the most important part to ensure the antenna match with our FPV system to provide you with the most efficient directional antenna.

Helical 12 turn is designed to get most range out of your 5.8GHz gear. Covering 100~120 degree signal beam and providing highest gain available on 5.8GHz while maintaining efficiency, we recommend using this with our ORT cocktail Omni antenna to get the best performance.
